Sealine S29 2005 vs Sealine S335V 2021 — Same Brand, Different Boat

The Sealine S29 2005 vs Sealine S335V 2021 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

The power gap is worth calling out. Rated to 300 hp, the Sealine S335V 2021 has a 140-hp advantage over the Sealine S29 2005's 160-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 126 gal and 125 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Sealine S335V 2021 is rated for 10 passengers, while the Sealine S29 2005 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sealine S335V 2021 could be the deciding factor.

Bottom line: Choose the Sealine S335V 2021 if your priority is putting more people on the water — it handles 10 passengers and at 33,1 ft it has the deck room to back that rating up comfortably. The Sealine S29 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.

Sealine S29 2005 vs Sealine S335V 2021 — Common Questions

Which is the larger boat — the Sealine S29 2005 or the Sealine S335V 2021?
The Sealine S335V 2021 is the longer of the two at 33,1 feet overall. The Sealine S29 2005 comes in at 30,0 feet, making it roughly 3,1 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Sealine S335V 2021 is rated to a maximum of 300 hp, giving it the larger power ceiling. The Sealine S29 2005 tops out at 160 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Sealine S29 2005 is Coast Guard rated for 9 passengers, while the Sealine S335V 2021 is certified for 10. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Sealine S335V 2021 measures 139" wide, compared to 126" for the Sealine S29 2005. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
How do the fuel tanks compare on the Sealine S29 2005 and Sealine S335V 2021?
Both boats carry similar fuel loads — 126 gallons and 125 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Sealine S29 2005 and Sealine S335V 2021 from the same manufacturer?
Yes — both the Sealine S29 2005 and the Sealine S335V 2021 are built by Sealine. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
